China's Tributary System and National Security in the Song Dynasty

Abstract China's ancient tributary system not only served the vanity of the dynasty but had multiple political implications, closely tied to the dynasty's national security. The Song dynasty's [960-1279] notion of security followed an overall policy of guarding the dynasty against external threats, surrounding barbarian nations, and maintaining domestic order. The stability and eventual collapse of the tributary system were closely tied to the domestic security of the Song dynasty and to the security of all the countries that participated in the system. The system constituted a dynamic and interactive security community.
